Lamb rearing involves the care and feeding of young sheep from birth until weaning. This stage is the most rapid growth period in a goat’s life cycle. Proper management and attention during this time are essential for ensuring healthy development and improving overall productivity in the flock.
Newborn lambs have several unique physiological characteristics that require special care:
1. Their thermoregulation system is not fully developed, making them highly sensitive to environmental temperature changes, especially in the first few hours after birth. Exposure to cold can lead to respiratory issues like colds or pneumonia. Lambs born during colder seasons should be kept warm and protected from drafts.
2. Newborn lambs have a weak immune system and poor adaptability. They rely entirely on colostrum, the first milk produced by the mother, which provides essential antibodies and nutrients for survival.
3. Their digestive system is underdeveloped. Milk is directly transferred from the esophagus into the stomach through the esophageal groove, bypassing the rumen. Since their digestive enzymes are not yet fully functional, and intestinal reflexes are weak, they are prone to indigestion and diarrhea.
4. The liver function of newborn lambs is still immature, resulting in limited detoxification capabilities and reduced metabolic efficiency in breaking down and synthesizing substances.
To ensure the health and growth of lambs, farmers should provide clean, warm housing, ensure timely access to colostrum, monitor feeding patterns, and maintain good hygiene practices. Early intervention and proper nutrition during this critical phase will significantly impact the long-term performance and productivity of the animals.
